From the Desk of the Director,
Symbiosis Centre for Management and Human
Resource Development
Welcome to SCMHRD ‘Lean and Six Sigma Excellence Awards, 2018’.
In today’s crisis struck world, very few think in terms of growth. One needs to
consistently improve quality while aggressively reducing cost. Lean and six sigma
methodologies empower organizations to achieve these goals even in adverse economic
situations. The sooner we realize this, the better.
We strongly believe that Six Sigma is not just a methodology, but a way of life. The
organizations are yet to mature in this concept.
We, as an institute, wish to act as a catalyst in bringing about this awareness by
felicitating those who have reaped the benefits of using six sigma methodologies.
We, at SCMHRD, constantly strive for perfection in every endeavor that we undertake.
We thank the corporate for enabling us in grooming our students in this regard and also
for making this event a well branded one in an international context.
Best Wishes,

Applying Lean for Streamlining Client Conversion Activity
The customer is a Global Custodian Bank (GCB), one of the oldest institutions in North America
and one of the world’s largest asset management companies with trillions of USD under
management. It is responsible for custody and administration of 11% of the world’s total financial
assets and 40% of the US mutual funds market. It also provides 80% of the world’s largest money
managers and asset owners with foreign exchange and transition management services, and
quantitative research and technology-driven tools.
Wipro is engaged with the GCB in a large multi-year engagement for 24x7 for L4 support.
About Project
Project is designed to support and maintain one of the Data Warehouse Application for the client. It
provides a complete middle and back office solution to clients. It gives asset owners and managers a
dynamic, customizable, and scalable self-service platform for all their data needs. Powered by
superior accounting and performance capabilities and fully integrated with award-winning
information delivery capabilities, it provides an end-to-end solution. This application is an Oracle
Database, as a DataMart for the temporary storage sets for Data received from one of the upstream
application. Application is responsible for the delivery of extracts to majority of clients and third
parties. All these data extracts are extremely time critical. It is a high availability application which
needs to achieve predefined client expectations and SLAs. Even the slightest of outages on the
application can have huge financial and reputational losses to the company the application caters to
end users all over the world hence needs to be up and running 24x7, 365 days with minimal planned
downtime or outages. On an average there are 3 Client conversions every month
Problem
Client conversion activity is critical client onboarding process which involves end-to-end
environment configuration and testing of data flow and delivery of data extracts. Conversion
activity is highly effort intensive and time critical process with multiple manual activities would
take more than 70 Hours/Conversion. The success rate of the conversion was 46% leading to huge
rework effort and delay in end client onboarding. Delay in client onboarding had huge financially
loss to end client and financial penalties for customer.

Lean Tenets Applied
Fishbone analysis was applied to identify the problems
which are associated with the conversion activity.
• Unstructured process
• Issues while processing Data
• High MTTR
• Infra Issues The manual tasks were identified and many of them were
Automated to make the process mistake proof and save
manual efforts.
• Manual deleting of aged log files.
• Manual refresh of data
• Manually triggering of data processing.
5 WHY Analysis was applied to identify the root cause of
application issues.
• Issues with data rearrangement
• Issues with data refresh
• Unstable Application instance
Information Spaghetti was applied to stream line the
communication channels during Conversion activity
• The waste in the communication process involving
multiple parties.
• The number of communication channel came down
from 12 to 2 Standardization was applied to streamline the Conversion
activity.
• List of activities along with the time lines [pre and
post conversion]
• Details of known issues & Link of the SOPs
• Contact list of the Team involved during
conversion activity etc.

Storage Space Optimization and SAN Recovery
The Client
SNXT is a remote support center where infra-management is done remotely for multiple customers
on shared basis. One of the domain/technology supported is Storage domain. 45+Customers
supported by domain are from all the different vertical i.e. BFSI, Government, ENU & Retail.
Deliverable
As part of domain support from SNXT remote infrastructure management team, Storage team has to
ensure the storage space consumption below the threshold of 80% to avoid application slowness,
business downtime etc as per the defined service levels. Team has to maintain sufficient free space
for the high availability of server/service for the customers DC Infra.
VOC:
In the Q1 of FY 2018-19, Storage team received multiple Customer concerns related Server
slowness, Drive disconnection and Performance issues. Team analyzed the storage health report of
May’18 to Jul’18 and observed that, storage space consumption was crossing the threshold limit of
80% (was varying from 85% to 95%).
High storage space consumption leads,
• Application slowness
• Business downtime
• Revenue loss to customer
• Reputation damage
• Low CSAT
Page 13
AAROHAN 2018
SYMBIOSIS CENTRE FOR MANAGEMENT AND HUMAN RESOURCE DEVELOPMENT
11
Business Situation
DC IT Infra is backbone for the entire IT services it is important and critical that always sufficient
storage free space should be maintained & consumed space should be under the threshold limit.
Being a shared infrastructure for multiple servers belonging to multiple Customers space constraint
will lead to range of business issues to Customer including business outage.
We have intended to work on Storage Space Optimization in shared domain accounts, to decrease
issues related to “space constraints”. This will further contribute in decreased risk of unplanned
downtime in DC operations which in turn will be resulted in avoidance of potential productivity
leakage from engineers, increase operating margin for Centre & enhanced the customer satisfaction.
How we Helped…
Automation: With the help of automation Script, team has automated the SAN backup activity,
which is prerequisite for performing any storage related activity and is resulted in elimination of
manual intervention, reduced the time for taking the SAN backup and also Team has enabled IOPS
reports which help in identifying the live status of live read & write operations of storage volume.
Poka-Yoke (Mistake Proofing): User ID has been created with the security admin property and has
only the authority to execute Config-upload command which will avoid wrong command execution
from Engineers while taking SAN backup.
Capacity Planning: Individual application wise storage space allocation/reclamation trends are
analyzed and reports were shared with Customer.
Individual month wise storage space allocation/reclamation of Storage product wise trends are also
shared with Customer as a part of pro-active planning.
Standardization: Mandated not implement any critical changes which are cause for business
services unavailability. Created a standard operating procedure for storage space reclamation. To
enhance the Engineer’s knowledge internal training sessions were conducted

Challenges faced
• Convincing the Customer access privilege and space for saving SAN backups
• Inter domain coordination
• Coordination with Vendor/Customer
Benefits
• Business Benefit: Reduced the time taken for
SAN switch configuration backup activity
from 18 hrs/week to <1hr/week. Which
resulted in operational cost saving of INR
1.2MN/Year.
• Customer Benefit: Due to our extensive
efforts in reclaiming the space, we were able
to benefit Customer by reclaim 80TB space,
which is equivalent to the cost saving of
approx. INR 6MN.

Productivity Improvement for a Major Step
Problem Statement:
During the period 11th Nov’17 through 29th Dec’17 average Ckmph for subject step was around
4.08 as against target of 4.3 for Q4’17.
Wipro team studied the process in detail through Value Stream Mapping (VSM). This study helped
us in identifying Non-Value adds in the existing process.
In the existing process, Operator had to revisit same set of evidences to model a particular parameter
thereby spending additional time in modelling the complete AOI. Wipro recommended a change in
methodology (Pan and Scan) which reduced the time spent in referring to the same evidence
multiple times.
Approach:
• Pilot team comprising of 7 people worked on this step using new methodology that fetched
good productivity benefits without compromising on quality.
• Based on the benefits realized from the pilot batch, all the teams were asked to follow new
methodology.
• This proactive idea of Wipro was highly appreciated by the client and they gave approval to
proceed with the strategy in order to improve the overall product. Wipro took ownership on
the end-to-end process and demonstrated capability to deliver It on time. Wipro modified the
process workflow and provided the quick action plan for output improvement.
• Client also implemented the new change in their latest version of the tool. This action plan
helped in sorting out the issues and successfully completing the project with benchmark
performance
Business Benefits
• Productivity improved by 59%, from 4.08 Kmph to 6.5 Kmph
• 4K+ hours/month of productivity benefits realized with a $ impact of $20645
• Wipro’s new approach was deployed in the customer tool at an Enterprise level.
• Wipro’s new work approach helped the business to enable the deployment in the step, it
helped the customer to reduce the rework time by 50%.

Reduction in Cycle Time for Sales Live Chat Process
Necessity of doing this Project and Current Status
This project was done for one of the largest telecommunications company, offering a full range of
communication services and competing in all telecommunications markets. Sales Chat is one of the
processes outsourced by this Australian telecom giant to Wipro. Wipro is responsible for handling
chats and for converting them into sales (pertaining to core and ancillary).
It was observed that the average chat cycle time in the period between 1st Dec 2016 and 15th Jan
2017 was 1567 seconds and a reduction in NVA by 15.76% approx. has a potential to create
capacity in the process thereby increasing the number of sales and in turn increase Telstra’s revenue
by over AUD 15 Million. The project will also impact customer experience and NPS for the
process.

Improvement Opportunity
A Value Stream Map was drawn to understand the steps at a click level and determine the flow of
the process in order to identify the various wastes associated with it. Key inferences drawn are as
given below
✓ Wait time contributed to 12% of the total time since the advisors had to wait in chat to get
sales reference ID from the customers as well as for customer response to chat and system
latency
✓ Over processing contributed maximum to the total waste as probing and need analysis were
not standardized and a lengthy process was followed for account authentication
✓ Value Add contributed to only 24% of the total time
✓ A lot of time was taken in referring to multiple documents, websites, SOPs and chat window
✓ Advisors had to complete multiple documentation post completion of one chat and before
initiating another
Page 17

Solutions and Implementation Plan
✓ Product specific canned responses, soft responses for objection handling was prepared by
the training team and approval taken from the customer to implement the same
✓ Mistake proofing of standard responses
✓ Need analysis tailored for both new and existing customers to ensure continuous flow in the
process
✓ 5s technique implemented to ensure advisors were able to search for the required
information faster and lesser documents were referred to
✓ Kanban used to signal to supervisors in case the chats went beyond 30 minutes of AHT
✓ Process change was implemented to ensure that the advisors don’t need to wait in the chat
to get the reference ID
✓ SMED used to reduce the change over time between two chats
Risk analysis was done before implementing the solutions and a sign off was taken on the To-Be
SOP. Control Plan and Control Charts were rolled out to ensure the metric was monitored and
controlled by the project team.
Metric Improvement and Benefit
Post improvement of the metric, hand off document was signed off to transfer ownership to the
process owner. Approvals was taken from the concerned stakeholders to close the project
Benefits Realized:
Annualized increase in revenue for Wipro worth AUD 261,744 or INR 1,27,01,942

CPE Cycle Time Reduction
About Client: Client is one of the UK’s leading telecom service provider operating in more than
170 countries in the world. Wipro’s engagement with this client includes O2C (Order to Cash) and
operations handled from Pune & Chennai locations. Global service is one of the process where
Wipro is responsible for End to End delivery; starting from Sales order to the Installations of the
services at client’s locations.
Business Challenge: The process was facing the challenge of higher delivery timeline of
CPE/routers; ~70 days against the target of 50 days. This has resulted revenue loss, unnecessary
supplier cost for access & led to customer dissatisfaction during the period of May’16 to Aug’16.
The reasons were unknown and process had to deal with multiple escalations during that period.

Program Weight Loss by Incident Reduction
The Client
Service NXT is Wipro’s next-generation Integrated Services Platform for Remote Infrastructure
Management, designed to Improve Service Resiliency, reduce operational costs and drive closer
Business alignment.
Currently Service NXT supports 100+ customers, 13+ technical domains, 20+ services across 24*7
for India business Wipro.
Deliverable
An Incident is unplanned disruption /degradation of service. Service NXT being a remote
infrastructure management team, have to ensure the high availability of Customer infrastructure by
managing the Incident on time with minimal impact to Customer.
VOB / VOC:
Issue of increasing Customer business impact hours, due to increased incident count was one of the
major point of discussion during Governance / review meetings.
Rise in incident count was further contributing in increased unplanned downtime, in DC operations,
which in turn leading to potential productivity leakage from engineers. Also decreased operating
margin for Centre & increase in customer dis-satisfaction.
Business Situation
▪ We have evidenced a surge in Incident following business dynamic of multiple client
supported for remote DC infrastructure management. Which was leading to degradation of
service and intern influencing to Operation cost for organization and hampering customer’s
perception.
▪ Considering DC IT Infra is backbone for the entire IT services it is important and critical that
these incidents must bring under control, to improve the Cost of operation and CSAT. Overall
reduction in number of Incidents will lead to a decreased unplanned service downtime of DC
operations and better response, resolution from engineers, as they can concentrate more on
genuine Incidents.
▪ As a part of Incident reduction drive, we have envisaged to reduce the Incidents by 40%.

Ashok Leyland Limited
To reduce the rejection of the Synchro parts from current level of 1070 PPM
to 535 PPM (50% reduction) at Heat Treatment line by Dec’17
Executive Summary: Ashok Leyland has seven manufacturing locations based at Chennai, Hosur
(2 plants), Ennore, Bhandara, Alwar and Pantnagar. We are representing Bhandara Unit, a
transmission plant manufacturing Synchro-mesh Gear Boxes with technological collaboration with
ZF - Germany. The Plant is having state-of-the-art machinery and equipment to produce world class
transmissions. Organization is becoming lean not only to sustain competitive edge but also to
become a global player. Our Bhandara unit has many accolades to its credit; some of them includes
India Manufacturing Excellence Award, Rajiv Gandhi National Quality Award, Ramakrishna Bajaj
National Quality Award, LESSA’2013 Runner up award, Golden Peacock National Quality Award,
CII EXIM bank award etc.
Problem Selection & Linkage to Strategy: Ashok Leyland has driven various initiatives to
improve the customer satisfaction by solving the various customer concerns (internal and external)
by using lean six sigma approach. This has prompted to revisit and reduce the rejection of synchro
components. The high rejections of the synchro parts at heat treatment impacting the delivery
schedules of entire Bhandara plant and additional manpower was required which further increases
operating cost. Hence the project has been taken by heat treatment team to solve the above-
mentioned concern. This will result in financial saving of INR 2.06 lakhs per annum.
Scoping of the Problem: From Fig a, P chart concludes that rejection PPM of synchro parts was
1071 PPM for last 9 months. The pareto chart in Fig. b shows contribution of the rejection of
synchro parts at heat treatment. Fig. c shows reason of rejection of synchro parts at heat treatment.
Fig a Fig b Fig c
Define: The charter was approved by the management, a SIPOC diagram was done to understand
the relationship right from Supplier, Process to Customer. Relevant CFT team was accordingly
formed and driven by GB, with the support of BB and Sponsor. Framework for reviews with all
stakeholders finalized. The team worked on the process map and identified the KPIV and KPOV’s
in shown in Fig d.

Project Category: Six Sigma -DMAIC
Six Sigma Approach
Six Sigma strategies seek to improve the quality of the output of a process by identifying
and removing the causes of defects and
minimizing variability in manufacturing and business processes. It uses a set of quality
management methods, mainly empirical, statistical methods, and creates a special
infrastructure of people within the organization who are experts in these methods.
Why This Project:
Total Indicating Reading (TIR) causing poor VDM index, Generating more scrap in next
processes. The selected part having high TIR issue causing imbalance which results more
machining cycle time as well as quality deviation for TIR Fallout and TIR Scrap.
Define Phase: Define the system, the voice of the customer and their requirements, and the
project goals, specifically.

• The project was identified based on internal Departmental KPI Scorecard where
RED Quality KPIs need to be improved with respect to VOC (Voice of Customer)
• Project organization has defined to drive Six Sigma project with cross functional
team involvement from Quality, Production, Maintenance, Engineering to do
teamwork through DMAIC approach to improve the targeted results (CTQs) within
timelines.
• Project kicked off done after initial financial validation and approval from sponsor.
Measure Phase: Measure key aspects of the current process deviations and collect relevant
data; calculate the 'as-is' Process Capability.
• Team collected the base line data for project Y by studying the Critical Processes
from Process Flow Chart. Base line taken of last 6 months’ data and target set.
• Total Gauge R & R (MSA) for TIR measurement system done
Analyse Phase: Analyze the data to investigate and verify cause-and-effect relationships.
Determine what the relationships are, and attempt to ensure that all factors have been
considered. Seek out root cause of the defect under investigation.
• Series of Brain storming sessions were conducted to identify the potential X’s and
done SIPOC and Process Map with 38 Xs taken forward
• Further screening of X’s is done by Cause and effect Matrix filtered 13 Xs and
FMEA further drilled down 3 Xs for high RPN actions.
• The relationship of this vital X’s with TIR Fallout is validated in each stage.
• One-way ANOVA Analysis for Trimmed jobs and padded jobs (P value <0.5).
• Scatter plot for TIR position Analysis.
Improve Phase: Improve or optimize the current process based upon data analysis using
techniques such as scientifically experiments, Improvement Action Plan & validation and
standard work process. Set up pilot runs to establish process capability.
• Cause Validation plan and Improvement actions for Punch Compensation for
Trimmer punch and Padding Die.
• Compensate Control cooling effect and maintain TIR high point at center.
• 2-t Sample test for TIR mean (Decreased) and Box Plot.
Control Phase: Control the future state process to ensure that any deviations from the
target are corrected before they result in defects. Implement control systems such
as statistical process control, production boards, visual workplaces, and continuously
monitor the process. This process is repeated until the desired quality level is obtained.
• Significant change in Production rate is observed and same confirmed using 2
Sample t test.
• To sustain the improvement, Implementation of 4M change management.
